Math Mammoth Grade 5-B worktext (Light Blue Series) is the student worktext covering the second half of fifth grade math in the Math Mammoth curriculum. This is the 2023 edition.

The books starts out with chapter 6, where we study multiplying decimals by decimals, dividing decimals by decimals, and conversions between measuring units.

Chapter 7 covers the addition and subtraction of fractions, and chapter 8, the multiplication and division of fractions.

Chapter 9 is about geometry. Students learn to classify triangles and quadrilaterals, and study the concept of volume in the context of right rectangular prisms.

Features

- Math Mammoth focuses on conceptual understanding. It explains the "WHY", so your children can understand the math, not just learn "HOW" to do it.
- Concepts are often explained with visual models, followed by exercises using those models. These visual models can take the place of manipulatives for many children; however, it is very easy to add corresponding manipulatives to the lessons if so desired.
- The curriculum is mastery-oriented. This means it concentrates fairly long on a topic, delving into its various aspects. This promotes conceptual understanding, as opposed to spiral curricula that often tend to jump from topic to topic too much.
- Very little teacher preparation is required. :)
- The curriculum has no separate teacher's manual nor is it scripted. The introduction to each chapter has some notes for the teacher concerning the material in the chapter. All the instruction is written directly to the student in the worktext, and there also exist accompanying videos where you can see Maria herself teach the material.
- After each chapter introduction, you will find a list of Internet links and resources (games, quizzes, animations, etc.) that can be used for fun, illustrations, and further practice.

Please note this book is spiral (coil) bound.

The first half of 5th grade math is covered in Math Mammoth Grade 5-A worktext (available separately at Lulu). Also available for grade 5 are the answer key book and a book containing cumulative reviews and chapter tests.

Soft comfortable very good pillow
Size: King (Pack of 1), Color: White
I really love my new pillow it's great and comfortable. Yes, it has a little smell, but if you wash the pillowcase and put the pillow on the window for a day you won't notice anything anymore.

Best place for head
Size: Queen (Pack of 1), Color: White
Do you love not getting sleep and sweating all over your pillow at night when you are asleep? If so then don't buy this pillow! If you want a good nights sleep and cool pillow like me this is the one. Ive always been ehh towards spending so much on a pillow but its 100% worth it, I sleep so much better and it forms to my head and keeps me cool at night. Great support even for my big head and comes with a bag of extra stuffing if you want to have a little more firmer pillow. Highly recommend

Oversized
Size: Queen (Pack of 2), Color: White
I have chronic neck pain. I am forever buying new pillows. Sometimes I think I found the perfect pillow but then three months later they’re losing their loft. I thought I would give these pillows to try since the stuffing is removable. Now these pillows are really oversized. To the point where I thought that they had sent me king-size pillows but I double checked the packaging and they were Queen. I ended up having to buy king-size pillowcases for them because they just barely fit in the queen size and the pillowcases would always end up pulling back from the edge. So that’s a negative one star there. Now I’ve been sleeping on these pillows for a while and they have held up well. I did end up removing some of the stuffing because it was just too much. I’m a side sleeper and when I use this pillow, it does a good job of keeping my neck in alignment. However, the pillow tends to migrate up as I sleep. Or I tend to slip down off the pillow, either or. So that’s why I’ve removed a second star. Maybe if I removed more stuffing that wouldn’t happen, but then I feel like the loft would be too little. I will say that these provide great support when sitting up in bed reading or watching TV. So would I buy them again? Probably not. Am I going to keep using them? Yes

The most comfortable memory foam body pillow
Size: Body(Pack of 1), Color: White, Size: Body(Pack of 1), Color: White
Homelab adjustable shredded memory foam pillow hugs to the curve of my body so comfortably at night. Since I’m a side way sleeper, it’s really nice to have a pillow to prop up my knee on the side. The pillow arrives in a vacuum sealed bag, and it bounced into shape quickly. The pillow cover is made with a really nice material, it’s soft and thick and it stays cool. The shredded memory foam inside makes it so easy to adjust the firmness of the pillow. I think this pillow is made with high quality material and would recommend it to all the side sleepers.

Awesome pillow
Size: Body(Pack of 1), Color: White
So although the pillow is pictures as a head pillow, I actually use this as a body pillow because it's as long as one. That's fine by me because it's somewhat firm but gets soft as your body heat warms it up. I've been using it for a few weeks now and haven't noticed any bad misshaping or anything. It's shredded memory foam so like all shredded memory foam pillows you've got to fluff them a little.
